ら出てくることである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved container that can be ruptured to release the contents. 71) Barrel containers (bags) are used to store single-use items such as ketchup, syrup, etc. Conventional barrel containers (bags) are made of flexible material such as thermoplastic film. The periphery is heat-sealed (
heat sealed). The problem with containers that use 71) is that in order to push out the contents, it is necessary to break the heat seal, which is difficult and the contents can come out from unexpected places.

る。The container is provided so that it can be easily opened at a desired location by applying the voltage. The seal is provided with a substantially V-shaped protrusion, which is rubbed so that the apex of the figure 7 points toward the inside of the container. When external pressure is applied to the wall of the container, the seal begins to break at the apex of the figure 7 (71), which propagates in a predetermined direction, causing the contents of the container to flow out in a predetermined direction.

The sheet material is preferably a heat-sealable single or multi-layer plastic film, but the film may also be laminated to another material such as paper or metal foil. If the flexible material consists of more than one layer η), it is preferable that the inner layer is made of a heat-sealable resin.

。The holding part of the wall uI is the peripheral part un, 1121. u3+,
■Seal each other along the lines. The seal is preferably a heat seal, but an adhesive may be used depending on the case. Although the embodiment shown in the figures is sealed around the entire circumference of the container, other embodiments are also possible. For example, a sheet of flexible film may be folded in two and the left and right sides and the upper portion sealed, so that the lower part of the container is formed by the folded portion. It may also be made by sealing both ends of a seamless tube. In either case, the container is sealed airtight and provided so that an internal pressure is created within the container that is substantially equal to the pressure applied by the external force.

は尖っているのが好ましいが、丸められていてもよい。The structure of other parts of the container is the same as the conventional one. The seal shape formed with the peripheral edge U includes a seal portion that protrudes from the inside of the container, and the shape of the protrusion is provided so as to be substantially V-shaped. In this case, the apex of the figure 7 is provided towards the inside of the container. As mentioned above, when pressure is applied to the container by pushing, pressure is generated inside and the seal begins to peel off from the top of the V-shape αω. As shown in Fig. 3, the l-shaped seal part opens in a well-defined path.The reason why the peripheral part α4 is opened is because this part is provided with a ccV-shaped seal part. This is not because the peripheral edge aυ is made weaker than [121% a~.] Of course, it is also possible to make the peripheral edge σ weaker than other parts, if necessary. The optimum shape of the shape σ9 is determined by the strength of the seal at the volume shoulder edge a of the container. For example, if the apex angle is reduced, the container will be easier to open, but at the cost of l
This capacity decreases. The optimal shape of the V-shape Uω for any container can be readily determined by mechanical experimentation. 71) For most purposes, it is best to set the apex angle to be substantially 30-120';
It is preferable to set it to 5 to 90''. The apex of the 7 character 115+ is preferably pointed, but it may be rounded.

Ｖ字形の辺部は直線のほか曲線になっていてもよい。The sides of the V-shape may be curved in addition to straight lines.

ともできる。Figure 4 shows 1! li! In the example, an unsealed area αe is provided at the peripheral edge (J41), and the above area αG
constitutes a passage extending from the peripheral edge +14+ end force) to the V-shaped part a9. The unsealed area αe is provided within the passage through which the tearing of the seal propagates. therefore,
When external pressure is applied to the container, the rupture starting from the apex of the square shape u51 propagates to the area ae and the contents are forced through the passage defined by the area αQ. If desired, a hard plastic tube (not shown) can be attached to the unsealed area [161] to create a passageway to facilitate ejection of the contents in the container.

The propagation distance of the dehiscence part can be shortened.
